Optimizing High Data Rate Transmission using 64-Channel DWDM System with DCF and NRZ Modulation

Abstract

The ideal way to approach a modern communication system that needs to be improved and used for high data rate transmission is with DWDM. In this study, we employ DWDM communication systems with 64 channels, different data speeds, and a dispersion compensation method. The pulse enlargement effect of transmitted light in the optical fiber is constrained by the dispersion reimbursement approach. DCF brought are simulated, analysed, and done to explore the sixty-four channels DWDM machine using DCF for NRZ modulation format at varied Bit Rate with several energy tiers to resolve the dispersion effect. The suggested method for 10 to 40 Gbps uses an NRZ modulation technique with an erbium doped fibre amplifier (EDFA) over a single mode fibre transmission distance of 40 to 160 km and a dispersion compensation fibre of 8 to 32 km (DCF). The developed model's performance is measured in terms of Quality factor, Bit Error Rate (BER), Eye Height, and Threshold at two input energy levels from an optical power source over the 0.625 Tbps to 2.5 Tbps communication capacity.
